Carrier NVR AM Set tings

The ONcore c arrier can store config uratio n s ettings in i ts N VRAM (non-vol atile random access me mor y), which it can use whe n powering on in either a man aged or u nmanage d hub. Two NVRAM DIP switch es control whether or not the ca rrier uses NVR AM settings. For informatio n on setting the NVRAM DIP switc hes, refer to Enabling or Disa bling NVRAM Configuration on page2-10.

When the ONcore carrier ships from the factor y, the NVRAM doe s not contain any configur ation settin gs.

The carrier stores configu ration setti ngs in NVRAM when eithe r of the following oc curs:

You use a D MM configu ration com mand or an SNM P manager to change a carrier configuration setting. For example, if you use the SETPORT NET WORK com mand to chan ge a carr ier por t network as signm ent, the carrier stores the new n etwork assignme nt in its NVR AM.

The carrier stores the new setting as soon as you issue th e comman d. The SAVE comma nd does not affec t the contents of NV RAM.

■

The DMM sends configuration settings to the carrier during a hot swap. For a definition of hot swap, refer to Ho t Swapping an ONcore Modu le on page 3-7.

Carrier DIP Switc h Settin gs

The carrier contains a DIP switch tha t you can us e to configure networ k assignme nts. For more informa tion on DIP switch setting s, refer to Configuri ng the ONcore Carrier D IP Switches on page 2-9.

In some case s, the carrier uses default con figur ation settin gs contai ned in its software. The d efault netwo rk assignm ent for the ONcore carrier is Isolate_1.

Hot Swapping an

ONcore M odule

You can remove a m odule from the ONcore hub and install an identical module in the same slot with out powering off the hub. This is called a hot swap. Whether or not you hot swap the Edge Router modu le affects which configuratio n source the carr ier uses .

When you per form a h ot swap, the DMM tran sfers to the new carrier the configuratio n used by the old car rier. The new carrier saves the setti ngs in its NVR AM.

The DMM tr ansfer s the con figur ation to the n ew ca rrier o nly if it h as a sa ved configuratio n for the old car rier insta lled in that slot. The D MM saves the configuratio n when you pe rform one of the fol lowing:

■

Issue the SAVE command.

■

Use SNMP to mak e the configura tion chan ges to the carri er. The DMM automatical ly saves the changes .

■

Reset or power- cycle the D MM. The DMM a utomatic ally acquires and saves the NVRAM con figuration s of all instal led modu les.

If the carrier does not have config uration settings store d in NVRAM, it uses d efault settings. If the DMM detects a problem with the NVRAM configuration, it forces the carrier to use default settings. For example, if you install the carr ier with ports assigned to Ethern et_8 into an ONcore hub model that does not support Ethernet_8.

Troubleshootin g 3Com Carrier Prob lems

When you first instal l the Edge Router mod ule in an ONline or ONcore hub the Cisco engi ne runs a full set of hardware d iagnosti c tests. If the en gine fails diagnos tics, the Route r (RTR) LED does not illum inate or will flas h. This indicates a proble m with the rou ter hardware or software. Refer to the appropriate Cis co Systems troubl eshooti ng docum entation for co rrective action.

ONline and ONcore Edge Rou ters use a hardw are mailbox inte rface tha t allows the Cisco en gine to com municate with the 3Com car rier board during power up. If the 3Com mailbox doe s not establish co mmunication with th e en gin e, the foll owin g m essag e i s re por ted to the eng ine con sole port:

Troubleshooting Network Connectivity Problems

If the Edge Router module does not appear to be routing traffic properly on the network, it may indi cate that there is no connecti on to the network.

Try perfor ming one or m ore of the followi ng troubles hooting ac tions:

■

For ONline and ONcore Edge Router modu les only, use the 3Com managem ent interface (for exampl e, ONline manage ment modu le) to verify that the Edge Router mod ule backpl ane port is se t to the appropriate backplane network (channel).

■

Using the Cis co terminal inter face, verify that the following para meters are set co rrec tly :

■

IP address

■

Subnet mas k

■

Default g ateway

■

Use the ping utility to confi rm that there is netw ork conne ctivity.

■

Use th e cisco>show interfaces ethernet 0

command to verify that the inter face i s u p an d r unnin g. This com mand repo rts Ethernet s tatistics that aid you in tro ubl esho oting the netw or k.

If the inter face is down, you m ay need to use the C isco confi guration ed itor to is su e th e no shutdown
